1.4tdi smoking

Me even less. I would not recommend having the injectors cleaned but rather replaced, although on the PD engines the injectors are activated by a cam rather than by a solenoid or similar device as on most common rail diesel engines so it would be tricky to get to and replace.

You say that two injectors have been replaced; is any reason why the third one wasn't also replaced? It could be this one that's messing you about...just a thought

The third one I haventt changed cause I had it plugged on the diagnostic and the reading of the injector was close to as being new.
 
AMF is a PD engine, so there's no high-pressure common rail. Makes a leaking injector less likely...

White smoke or blue smoke? Smell of burning oil?
 
Some info on diesel smoke colour:
WHITE SMOKE occurs when raw diesel comes through the exhaust completely intact and unburned. Some causes of this include:

  • Faulty or damaged injectors
  • Incorrect injection timing (could be a worn timing gear or damaged crankshaft keyway).
  • Low cylinder compression (eg caused by leaking or broken valves, piston ring sticking, cylinder and/or ring wear, or cylinder glaze)

When white smoke occurs at cold start, and then disappears as the engine warms up, the most common causes are fouling deposits around piston rings and/or cylinder glazing. Use of our Flushing Oil Concentrate and FTC Decarbonizer address these respective problems.

Water entering combustion spaces will also create white smoke. Faulty head gaskets and cracked cylinder heads or blocks are a common cause of water entry, and are often to blame. Unfortunately, expensive mechanical repair is the only proper solution here.

I have found the problem. It was the injector seals that needed changing. Thanks guys
